Of course it is here to stay for ever (however long that is) but so
too is metal 3D printing which will suplement metal casting, extruding
and machining. See:

or http://tinyurl.com/y3spmdeo
and
https://www.3dsystems.com/sites/defa...?itok=DHYJGySs
or http://tinyurl.com/yyzzk34y
for examples.

I wouldn't be at all surprised if one day soon we get top end cameras
made with 3D printed titanium bodies.

"It is fabricated largely by 3D printing, using a method called
electron-beam melting. Its combustion chamber, injectors, pumps,
and main propellant valves are all 3D-printed."

"More than a third of the components in GE’s advanced turboprop
(ATP) engine, rated at 1,300 shaft horsepower, will be built through
additive manufacturing methods, a catchall term that includes 3D
printing."
